Shwup makes slideshows and movies from pictures. It could be used by students or teachers for pictures from any curriculum area. No place to add text, but you can add music. They have music you can choose from or you can upload your own MP3 files. This site is similar to Animoto. You can upload files or pictures from many different sources including Facebook, your computer, Picasa, any web page, flickr. One of the unique things about Shwup is that you can share it with others and they can add their own pictures and video to your file. The example they gave was a birthday party. Many people take pictures. You can create an album of your pictures, then request others add their pictures. That way everyone has all the pictures together in one album. This could be used by students for the International Fair. All of them could find pictures and put them together in one album.
